Budget ill treated me for switching to another insurance

So when I bought my vehicle through weelee I was given options of insurances and I chose budget insurance. As time goes they called me non stop introducing services that I felt I didn't need however they called everyday I was annoyed and found a better comprehensive insurance much lower that budget.I called budget to cancel their insurance and the lady told me that I have to R600 pro data wat wat of which I was willing to pay. To my surprise budget is on my credit profile with the debt of R2093.00 that I dint know of! I felt like it would have been better if someone called me and explain the whole process in a bit professional manner .Maybe the crime I committed was to switch the insurer.Now my credit record has been affected with no explanation at all. I am so disappointed with this company I felt I was ill treated 😪
